Andy Marsh has served as CEO of Plug since April 2008, guiding the company’s transformation
into a global leader in the hydrogen economy. Under his leadership, Plug has built the industry’s
first vertically integrated green hydrogen ecosystem—spanning production, storage, delivery, and
power generation—to help customers decarbonize at scale and achieve energy independence.
A forward-thinking executive with deep technical expertise and a strong commercial focus, Marsh
has led Plug’s strategic evolution from a fuel cell pioneer to a full-spectrum hydrogen solutions
provider. His vision and leadership have positioned Plug at the forefront of the global energy
transition, delivering breakthrough technologies and building long-term partnerships with industry
leaders like Amazon, Walmart, and Home Depot.

Prior to Plug, Marsh was co-founder and CEO of Valere Power, a power solutions company serving the
telecommunications industry. Under his leadership, Valere grew into a profitable global operation
with more than 200 employees and $90 million in revenue, ultimately leading to its acquisition by
Eltek ASA in 2007. During his tenure, Valere earned numerous accolades, including the Tech Titan
Award and Red Herring’s Top 100 Innovators.

Marsh is a recognized thought leader in the hydrogen and clean energy sectors. He is the former
Chair of the Fuel Cell and Hydrogen Energy Association (FCHEA), a member of the Hydrogen
Council, and serves on several boards, including GEVO, the UAlbany Economic Advisory Board, and
the Northern Ireland Delegation.

He holds a Master’s in Electrical Engineering from Duke University, an MBA from Southern Methodist
University, and a Bachelor’s degree in Engineering from Temple University.
